When you first fell in love, who did your first heartbeat go to?

The first time I had a heartbeat was when I was sixteen years old. You are that weak, pure and beautiful little girl with good grades. I was the naughty little boy who got the lowest grades. A gentle "I'm sorry" made you live in my ignorant heart. How could a boy lose to a little girl, and it was the girl I fell in love with for the first time. So I started studying hard. I want to get closer to you with results that can rival yours. When my teacher and mother were surprised that I suddenly became sensible and my grades slowly caught up. I'm hopelessly in love. Every improvement in test scores is a step closer to you in my heart. I want to walk to you step by step and keep pace with you. The days of studying hard are really bitter and tiring for me, who has always had poor grades, but when I think of you, all the bitterness turns into sweetness. On the day I got the college notice, I wanted to express my love to you. But you already have someone you love by your side. I can only murmur a smile and say "thank you" to you. Seeing your incomprehensible expression, I turned around and left as fast as I could. I was afraid that my tears would fall if I couldn't help it. A real "thank you". Without my love for you, I would still be a confused boy today. It is this love that makes me work hard and become much better than my original self. "Thank you" to the girl I loved.
